I've made good progress on measurement of my tremors using a LSM6DS33 and ATmega2560. I can log both gyro and accelerometer at 250hz. Offline I managed to determine the frequency of my tremors and can apply that code to the Arduino to measure frequency in real time. Now come the problems. The si…

You are correct. The code is missing a line. Corrected code: float a[8] = {0, 0, 0, 0, 10, 10, 10, 10}; //example square wave signal, period = 8 x sample time void setup() { Serial.begin(9600); //sample time = 10 ms, signal frequency in this case = 1/period = 12.5 Hz. //DFT calculated for …

Don't know much about the LSM6DS33 but I did see in Table 64 of the spec a register to enable a low pass filter LPF2 Enable. Have you been using that?
